IN SULATING-SUPPORT.

Application filed September 25. 1914. Serial No. 863,502.

7 '0 all whom itmqy concern:

Be it'known that. I, Crmnnns W. CUVELL,

. a citizen of the United States, and a resi dent of Wilkinsburg, in the county of Allegheny and State of Pennsylvania, have invented a new anduseful Improvement in In sulatin -Supports, of which the following is suitable reactance coi an angle of less than 180 degrees 'from each other.

a speci cation.

My invention relates to insulating supports for electrical devices, and it has special reference to supports which may be utilized upon current-limiting reactance coils of various diameters.

Inasmuch as the manufacturer is required to furnish a great number of reactance coils of different sizes andcnpaeities for a variety of operating and service conditions, it has-been substantial] impossible to design i; which all conform to standard and common dimensions. By ICll. son of this, it has been necessary heretofore to provide new insulating supports for each differently sized coil, thereby greatly increasin the number of manufacturing parts re uire and the attendant first cost of the col s.

Oneobject of my invention is to provide an insulating support that may be'employed in connection with reactance coils having widely dillering diameters and which conform, in genera to a certain general design.

Another object of my invention is to provide an insulatin support which will be mechanically rigi and easy to attach to a reactance coil.

'For a more complete understanding of my invention, reference may be had to the following description and the accompanying drawing in which Figure 1 is a view, partially in elevation and partially in section, of an insulating support built ;in accordance with my invention; Fig. 2 is a top plan view ofthe sup ort shown in Fig. 1, and Fig. 3

I is o'p'artia plan view, looking upward, of-

the bottom 0 a reactance coil. equipped with one of my insulating supports.

Referring to Figs. '1 and 2, I provide a top plate 1 having two oppositely projecting arms 2 andB which pre erably lie in the same plane and are angularly displaced A central recess 4 is formed intermediatethe arms 2 and 3 in which is so cured an upper end portion 6 of a built-up insulator 5. The upper'portion 6 of the insulator that is locatedtin the recess 1 is proruled with a corrugation 7 which is en gaged by cement 8 poured into the recess 4 Patented-Oct. so, 1917.

in order to rigidly hold the plate 1 upon the" insulat'or. cast iron foot'9 has an upper end 10 that projectsinto a recess 11 formed in the insulator The foot 9 is held rigidly in fixed relation to the insulator5 by means of cement S. In each of the arms 2 and 3 of the plate 1 is formed an elongated slot 12 which is disposed midway between the side edges and extends lengthwise of the arm.

By referring to Fig. 3, it will be a'ppa rent that my insulating support, by reason of, the angularly-disposed arms 2 and 3 and the elongated slots 12 formed therein, ma be applied to reactance coils of many di ferent sizes. A common form of reactance coil is shown in which conductors 13 are spaced from one another and rigidly held in fixed relationship by means oia series of built-up columns comprising insulating and;

radially extending cleats 14. Each of the insulating supports is :secured to two bottom I cleats 14, siibstantially' as shown, the cenadjacent to an intermed ate cleat. Bo

tral portion of the support being disposed ts 15 project through-the slots 12 in the arms 2.1

and 3, and are provided with nuts 16 to secure the support to the reactance coil.

' Because of the elongated slots 12 and their disposition in the arms 2 and 3, my insulaitin g supports may be expeditiously applied to a large variety of reactance coils having different. diameters. For instance, theradial cleats 14 may be spaced greater distances more than one insulating sup ort will be required for each 'reactance coi l WVhen it is desirable to dispose the reactance coil in a fixed position, bolts'may engage recesses 17 formed in the base of the cast iron foot '9. At the same time, the coil" is thoroughly insulated from the bedplate to which the foot 9 may be secured by rea- 10s son of the interposition of the insulator 5 which enga es the cast iron plate 1.

While I ave shoyin and described one embodiment of my.- invention, it will be understood that many modifications may be made -therein without departing from the.- scIpe of the appended claims.

aim as my invention: v 1; A support comprising a top plate having laterally projecting arms and an inter.

mediate recess, said arms being: provided with longitudinal slots that are spacedfrom each other on an arc having a finite radius 0- ofcurvature, s n-insulator having its upper end seatedin saidrecess, and a metallic foot secured to said insulator and insulated thereby from said 'top plate.

' 2. A=support comprising aplate. having laterally projecting arms which are provided with longitudinal slots thatare spaced from,

each other on the same circumference having 'u finite radius, a recessed insulator secured at its top portion tosaid top plate, and a so metallic foot which pro ects into the recess I :formed in the insulator.

3. Asupport comprising a member hav laterally and oppositely projecting. arms that are provided with elongated slots in their outer ends; the slots being spaced from each other on an archaying a finite radius of cur\'ature, a metallic foot, and an insulator interposed between said member and said metal 10 foot.

4.; A support comprising atop-plate hav- 'ing laterally extending arms that are prorided with slots at their outer. ends, the

angle included between the center lines through the slots being less than and I an insulating foot secured to the support intel-mediate said arms,

In testimony whereof, I.hare liereunto subscribed my name this 22 day of'Sept.
